Answer: 1.85€, 0.5€
Step-by-step explanation:
Given
Peter bought 5 pens and 8 pencils which costs 13.25€
The pencil is 1.35€ cheaper than the pen
Suppose the price of a pen and pencil is x and y
So, we can write
[tex]\Rightarrow 5x+8y=13.25\quad \ldots(i)\\\Rightarrow x-y=1.35\quad \ldots(ii)[/tex]
Solving the above equations, we get
[tex]x=1.85,y=0.5[/tex]
Therefore, the price of a pen and pencil are 1.85€ and 0.5€.

Each solar array wing on the International Space Station measures 39 feet by 112 feet. The scale drawing of a solar array wing shown below was made using a scale of 1 inch: 8 feet.
Write the ratio of the area of the wing in the drawing (square inches) to the area of an actual solar array wing (square feet) as a unit fraction.
The drawing is just a large rectangle with the length being 4.875 and there is noting for the width.
Answer:
39-112= -73 or 73
so 73+1/8= 81

Answer: x =67
Step-by-step explanation:
The equation to solve this is (x - 22) + 135 = 180
1) To solve for x, you must remove the parenthesis
x - 22 + 135 = 180
2) Simplify the equation...
x - 113 = 180
3) Simplify the equation
180-113 = x
3) Subtract to solve
180 - 113 = x
x = 67
Answer :
As shown in the figure the angles x - 22 and 135 lie on a straight line . So we may solve it using linear pair property that states that the sum of angles lying on a straight line is 180° .
( x - 22 ) + 135 = 180°Remove the brackets x - 22 + 135 = 180Subtract 22 from 135 and as 135 is is greater than 22 the sign will be positivex + 113 = 180Subtract 113 from both the sides x = 180 - 113x = 67°Thus the correct answer is option d that is x = 67
a line crosses through (-6,-2)and (2,10) determine the slope and y intercept for this linear relationship
Answer:
3/2
Step-by-step explanation:
The formula to find slope is y - y all over x - x or (y-y)/(x-x)
Let's start with the y's: 10 - (-2) = 12
Now the x's: 2 - (-6) = 8
12/8 or 3/2 is the slope
Two angles are complementary. The first angle is 2x degrees. The second angle is (3x +5) degrees. Determine the measure of each angle.
Draw the angles, write and equation and solve the measures of each angle.
HELP PLEASE
Answer:
70 and 110
Step-by-step explanation:
First angle -- 2x
Second angle -- 3x + 5
Therefore,
2x + 3x + 5 = 180
5x = 175
x = 35
Therefore, 2x -- 70
3x + 5 -------------110

Solve the proportion 40/z+1 = 15/6
Answer:
z = 15Step-by-step explanation:
[tex] \frac{40}{z + 1} = \frac{15}{6} \\ [/tex]
Cross multiply
That's
[tex]15(z + 1) = 40(6) \\ 15z + 15 = 240[/tex]
Send 15 to the right side of the equation
[tex]15z = 240 - 15 \\ 15z = 225[/tex]
Divide both sides by 15
[tex] \frac{15z}{15} = \frac{225}{15} \\ [/tex]
We have the final answer as
z = 15Hope this helps you
5. A card is chosen from a standard

8. We want to solve for a of the trapezoid area formula.
A = [tex]\frac{h}{2} (a + b)[/tex]
First off, we need to multiply both sides by [tex]\frac{2}{h}[/tex] to cancel out the [tex]\frac{h}{2}[/tex].
[tex]\frac{2A}{h}[/tex] = a + b
Now, we need to subtract b from both sides.
[tex]\frac{2A - b}{h}[/tex] = a
We get the answer to be:
I. a = [tex]\frac{2A - b}{h}[/tex]
